For those who may want to see more of the Junior Christian Science Bible Program, there is an episode of it (haven't watched yet, but it looks like it's a new production, not one of the original public television episodes) on myspleen.
edit: Just had a very quick look at this, and it appears to be Tim & Eric goofing around with D. L. Hart. It may well be funny, but nowhere near as insane as the original series must have been.
